Description Cells pentagonal in outline (19–29 μm long, 15–25 μm wide). Epicone conical and acute, hypocone rectangular, obviously truncated by the sulcus. Cingulum displaced approximately 1/4 of the cell length. Sulcus sinusoidal, with a tubeshaped structure, and extending into the epicone as a finger-like projection. Chloroplasts long and ribbon-like, arranged into bands on the cell periphery. Nucleus small and round, located at the antapex of the cell. Large ventral pore approximately halfway between the anterior sulcal termination and the beginning of the apical groove. Apical groove relatively short, covering 1/3 of the ventral epicone and 1/4 of the dorsal side. (De Salas et al., 2008). [details]
Harmful effect There are no harmful effects reported from nature, but the species has been found to produce a haemolytic karlotoxin analogue in culture and may therefore prove to be harmful to fish. Additional studies are needed [details]
